Waves and Modern Physics


If I have seen further it is by standing on the shoulders of giants.

I had the wonderful apportunity of teaching a summer course in the University of Rochester. The course was on Waves and Modern Physics. I had a great time teaching the course. I learnt a lot from it. It was my first experience as a teacher. I really enjoyed the lecture on Rainbow. The students were great. They asked many interesting questions and many times I did not know the answer myself. It was then when I realized the importance of the words which one of my friends once told me, "We learn Physics in two ways, either we understand it or we get used to it".  I found that in many cases, I had got used to the concepts without understanding it. So, it was nice to interact with fresh brains. What follows is the course website for PHY123.

 

 The course Physics 123 will cover Fermat's Principle of Least Time,  Geometrical Optics, Waves, Sound Waves, Wave Optics, Special Theory of Relativity, Photoelectric Effect, Compton Scattering, Radioactivity, Working of Lasers, Wave Particle Duality and Particle in a Box, Hydrogen Atom.

Prescribed Books: Giancoli, Resnik Halliday Walker, Feynman Lectures in Physics.
